Definitions

  • the invention relates to an airbag module having an adaptive influencing device according to the preamble of claim 1.
  • every gas bag in particular each front airbag, has a ventilation device, through which gas can escape from the gas space enclosed by the outer shell of the gas bag - in the following first gas space - upon impact of the person to be protected, so that kinetic energy of the person to be protected is dissipated and the person to be protected does not simply bounce back from the airbag skin of the airbag.
  • a ventilation device is simply a ventilation opening, in particular a ventilation opening in the gas bag envelope.
  • adaptive influencing means for influencing the shape of the gas bag or the pressure in the gas space are known in the prior art. If the shape of the gas bag to be influenced, a releasable tether is usually provided. Furthermore, adaptive ventilation devices are known which, in addition to the ventilation opening, have a throttle element which, in a first state, throttles the gas flow through the ventilation opening more strongly than in a second state. As a rule, in this case the first state is the throttled or even closed state and the second state is the less throttled, for example fully opened state.
  • an operating unit which makes it possible to Adaptive influencing device active - to an external signal - to transfer from its first in its wide state.
  • a pyrotechnically operating actuator has become known for this purpose.
  • the first end of a tension band with the throttle element and the second end of this tension band is connected to a pin of the actuator.
  • the actuator is in this case held in particular on the housing bottom of the gas bag module.
  • the throttle element is connected via the drawstring to the housing bottom.
  • the tension band comes with fully expanded airbag shell in a tensioned state, which holds the throttle element in its first state.
  • the tension element loses its tension and the throttle element changes into its second, namely its unthrottled state.
  • This technique works very well in principle, but has the disadvantage that inside the gas space of the gas roofing parts, such as the bolt, can fly around, and that within the airbag hull open flames occur due to the pyrotechnic charge. Furthermore, the pyrotechnic charge feeds additional gas into the gas space of the airbag shell, which is not always desirable.
  • the generic DE 10 2005 039 418 B4 proposes an airbag module with an adaptive ventilation device, in which the actuating unit is formed by a "small airbag module within the airbag module.”
  • the throttle element is the actual airbag by a second, small airbag inside the gas chamber
  • the shell of this second airbag - hereinafter referred to as a second shell - encloses a second gas space, which can be filled with gas by a gas generator in the form of a primer.And if this happens, the second shell then filled with gas raises it into shape
  • a disadvantage of this is that the second casing and the ventilation opening must be directly adjacent to each other, which is often very limited hard to realize. In particular, it is hardly possible to provide the ventilation opening in the gas bag envelope.
  • the present invention has the object to further develop a generic gas bag module such that a great structural and functional flexibility is given.
  • the adaptive influencing device is an adaptive ventilation device
  • This airbag cover can be the outer cover which separates the first gas chamber from the surroundings, or a partition wall cover which separates two chambers from one another. In the following, therefore, this shell is collectively referred to as "first shell".
  • a traction element is provided whose first end is coupled to the adaptive influencing device or which forms the adaptive influencing device and whose second end is coupled to the second sheath of the actuating device when the second gas space is not filled and is decoupled from the second sheath when the second gas space is filled.
  • the second shell does not directly influence the throttle element but by means of the tension element whose first end is coupled to the throttle element or forms the throttle element and whose second end is coupled to the second shell when the gas space is not filled and when filled Gas space of the second shell is decoupled from this.
  • a further advantage of the gas bag module according to the invention is that the actuating unit consisting of the second casing and its associated gas source can be designed as a standard module which is suitable for a large number of different types. different gas bag geometries, gas bag interior pressures and applications can be used. In particular, it is possible to use this standard assembly both as an actuating unit of an adaptive ventilation unit and as an actuating unit in a dual-depth airbag. This is not the case with the actuation unit of the generic DE 10 2005 039 418 B4.
  • the second shell can be arranged completely within the gas space enclosed by the first gas bag envelope.
  • the second end of the tension element is connected via a Aufbrechtell with the second shell as long as the second gas space is not filled.
  • This break-off compound is designed such that it breaks up when the second gas space is filled with gas and thus the second shell is expanded.
  • the break-up compound can be designed in particular as a tear seam. This embodiment has the advantage of a very simple manufacturability and a low weight.
  • the second end of the tension element is designed as a loop, which extends around the second shell when the second gas space is not filled.
  • the circumference of the loop is shorter than the maximum circumference of the second sheath when the second gas space is filled, so that the loop is opened by the expanding second sheath.
  • the second shell may be formed in particular as a metal foil, which has the advantage of a high resistance, especially against hot gases, which fill the first gas space has.
  • the second shell may be completely separate. But it is also possible that a portion of the first shell or a portion of a reinforcing layer of the first shell forms a part of the second shell.

L'invention concerne un module d'airbag comprenant une première enveloppe (10) qui entoure un premier compartiment de gaz (G1), un premier gonfleur qui sert à remplir le premier compartiment de gaz (G1), au moins un système d'action adaptatif qui sert notamment à agir de manière active sur la ventilation du premier compartiment de gaz (G1) ou sur la forme de la première enveloppe (10), et un ensemble d'actionnement (40) qui sert à actionner le système d'action. Selon l'invention, l'ensemble d'actionnement (40) comprend une deuxième enveloppe (44) qui entoure un deuxième compartiment de gaz (G2) et une source de gaz qui sert à remplir le deuxième compartiment de gaz (G2), l'état du système d'action étant modifié par le remplissage du deuxième compartiment de gaz (G2) par la source de gaz. Afin d'obtenir une grande souplesse constructive et fonctionnelle, le module incorpore un élément de traction dont la première extrémité (62) est couplée au système d'action adaptatif ou forme le système d'action adaptatif et dont la deuxième extrémité (64) est couplée à la deuxième enveloppe (44) de l'ensemble d'actionnement (40) lorsque le deuxième compartiment de gaz (G2) n'est pas rempli et découplée de la deuxième enveloppe (44) lorsque le deuxième compartiment de gaz (G2) est rempli (Fig. 2).
